Llama 2

From Meta

Welcome to the official Model Database organization for Llama 2 models from Meta! In order to access models here, please visit the Meta website and accept our license terms and acceptable use policy before requesting access to a model. Requests will be processed within 1-2 days.

Llama 2 is a collection of pretrained and fine-tuned generative text models ranging in scale from 7 billion to 70 billion parameters. Our fine-tuned LLMs, called Llama-2-Chat, are optimized for dialogue use cases. Llama-2-Chat models outperform open-source chat models on most benchmarks we tested, and in our human evaluations for helpfulness and safety, are on par with some popular closed-source models like ChatGPT and PaLM.
